(GRANTED UHDEB. THE PROVISIONS 01? THE ACT OF IABGH 3, 1921, 41 STAT.1., 1315.)

To all whom it may concern:

Be it known that I, Liionon citizen of the Republicof France, and aresident of Paris, France, have invented certain new and usefulImprovements in Oil-Gas Apparatus (for which I have filed applicationsin France on February 20, 1918, Patent No. 496,539, granted on August 6,1919, and in England on October 15, 1918, Patent No. 140,128, datedMarch 25,

1920), of which the following is a speci-.

fication. 1

The present invention relates .to the production of rich gases andliquid fuel by means of petroleum residues and other hydrocarbonproducts of low thermal value.

It is known that the use of blue water gas or other gas of low thermaland lighting value is becoming more and more general for heating orlightinga its heatin and lighting pro erties becoming increase I bycarbureting t e gas with hydrocarbon products of low value, such asby-products of petroleum, which are vaporized, in such 1 a manner thattheir almost complete, de-

com osition is effected and their transformation into hydro en andcarbon. This method, however, oes not obtain the desired pur ose. I

a The ob]ect of the present invention is'to increase the calorific andlighting value of .blue water gas or other gas of low thermal value; andaccording to the invention, the

vapors of petroleum residues are passed through retorts containingcatalyzers heated -tobetween 500 and 600 0. The heavy hydrocarbons splitup into vapors and gases consisting of non-condensible 'olefines andhgdro'carbons which distil-- paraffius, light over up to"150 bons. Thegases thus formed are andheavier hydrocarmixed with the blue water gasor'the like, whereas the liquid hydrocarbons which distil up to 150? C.may be used as fuel for explosion motors, Finally, a very small amountof carbon is deposited on the catalyzers.

.The catalyzers used may be metals such "as, copper or iron, in the formoffilings or' "powder, which are formed into briquettes by means of abinder (gum, glue, starch, and. .rthe like),

1 r In the accompanying drawing, Figure 1 -represents a diagrammaticvertical sectional BLANCHET, a

' catal view of a unitary retort embodying the invention, andFig. 2 is afragmented horizontal section taken through the catalyzing compartmentof the retort.

As shown in said drawing, the retort of the present invention comprisesa lower catalyzing portion or compartment A, in the mtoncn BLANCHET, orPARIS, FRANCE, nssxcnonmo LA soom'rn ms cumin ETA form 'of apa'rallelepiped,'-and an upper vaporizing portion or compartment B; thetwo. portions A and B being'made of a single iron casting which isheated by a furnace or other means (not shown). In the interior of thecompartment A are arranged channel-iron supports C carrying rows ofbriquettes D prepared as described abovep- These briquettesare placedside by side and fill the entire length of the channel-iron supports andthe available height of the compartment A. The vaporizer B communiscates by means of a pipe connection E with a tank F containing thepetroleum residues to be catalyzed, said pipe opening at its inlet endthrough the bottom wall of tank F and at its outlet end through one ofthe side walls of the vaporizer at H.

The petroleum residues contained in tank F and fed through ipe E are vaorized in the vaporizer B, wgnch is heated y reason of its directconnection to the catalyzing compartment A whereon it is mounted, bothcompartments fol-min parts of the retort, as already stated. he vaporsenter the zin compartment A through an opening an flow. through thecatalytic mass formed by the briquettes ,D, contact with whichdecomposes them into amixture of light hydrocarbon vapors and gas. Thismixture is discharged from the catalyzing.

compartment A through a pipe G which opens into a suitable condensingcoil J, the

latter discharging, inturn, into a tank K;. .The liquid condensatesdischarged from coil J collect in tank K and the gas, which i alsopasses from said coil into the tank,

escapes therefrom through the outlet pipe L, whence it is sent into gasgenerators in order to be mixed-with blue' water gas or other gas of lowthermal value. The light,

hydrocarbons obtained" by this process as previouslydescribed arelikewise recovered.---

The arrangement described above has the advantage of enabl' thecatalytic mass to be easily introduce 'into and withdrawn fi orn. thecatalyzing chamber or compartqf merit A for removing the depositedcarbonl. p

For this purpose it is sufficient to open the outerdoor A of saidcompartment and to withdraw in' succession the several channeliron"supports C with all the briquettes I thereom. The catalytic masscan thenJoev easily regenerated.
